Traditionally, managing the caches has required fairly simple algorithms that can be hard-wired into the chips.http://phys.org/news/2013-09-software-hardware-high-speed-on-chip-memory.html

He agreed with the position of Red Hat engineer and Linux kernel developer Ingo Molnar to drop support for Intel's old 386 microprocessors. For Linux users, the world is not coming to a halt. All it means is that the 386 DX33 chip will not be able to run in future versions of Linux, just in existing versions of the kernel. Intel 386-DX owners, for whatever hobbyist or other reasons, will not be able to enjoy the new Linux versions starting with 3.8. Molnár explained that the extra work involved in continuing support was greater than the returns in benefits.http://phys.org/news/2012-12-linux-intel-processors-ways.html
